In the world of immortal cultivation where the north and the south confront each other, Miao Shuo, the descendant of the "Burning Sky Valley" in southern Xinjiang and the chief disciple of the Fengge Sect, was expelled from the master by his master because of the loss of control of his natural "red sun spirit body". Later, he was regarded by the righteous as a monster and hunted to the north. When he was on the verge of death, he mistakenly entered the forbidden land of the Hege tribe, "Eternal Night Valley", and met Hege Yuxue, the young master of the Hege tribe who had been exiled here and whose left eye had the power of the ancient snow demon sealed.
One is a "demon" whose body is burned by flames and cannot survive, and the other is a "barbarian" young master who is heartbroken by cold and is on the verge of madness. In the snowy night, they are attracted to each other because of the extreme opposition between each other's powers - Miao Shuo's red sun fire can soothe Yu Xue's snow demon backlash, and Yu Xue's ice-cold power can suppress Miao Shuo's burning fire. A blood-based game allows two desperate souls to find the only possibility of survival in the blend of ice and fire.
"The fire in your body makes me feel... Less cold."
"If you live, I won't be crazy."
From the initial mutual use to relying on each other to withstand the wind and snow back to back, they concluded the most primitive symbiotic contract in the ice cave of Eternal Night Valley. However, when they walked out of the forbidden area, they faced not only the internal fighting among the tribes and the encirclement and suppression of the right path, but also the secrets of their life experience and the fate of their blood. Miao Shuo's mother is a princess of the Hege tribe living in the south, and Yu Xue's father is the enemy who was ordered to be hunted down back then.
When the truth about the fusion of fire and snow is revealed, and the disaster of imbalance between heaven and earth strikes, they must make the final choice between revenge and redemption, tribal survival and personal love.
"I would like to exchange a hundred miles of snowfield for a ray of fire in your heart."
"Then burn it. It would be better for me to be buried in the fire than to live in your eyes."
Purpose: Mutual redemption
